She has barely left her boyfriend's side since he was released from jail - but Karrueche Tran decided to show off a good deal of herself at a Free The Nipple party in LA.

The pretty 26-year-old model went braless for the bash at the Skybar in the Mondrian Hotel in LA - and opted for a side boob baring white top and PVC blush skirt.

Keeping her hair loose around her shoulders as she looked like she enjoyed a night on the tiles at the glizy fundraiser.

She later took to Instagram to gush about the cause.

"Me and the lovely @dolphindylan - Director of Free The Nipple.. Such a powerful and inspiring woman.. Literally super woman of our time.. Standing up for what she believes in! #Awesome #freethenipple #BlurryButYouGetIt," she wrote.

Free The Nipple is a US equality movement, which challenges laws across 35 states of the USA where it is illegal for a woman to be topless, which includes breastfeeding.
